IMPROVEMENT IN CENTRiFUGAL LIQUORING APPARATUS.

Specification forming part of Letters Patent No. 1,896, dated November 18, 1879; application tiled June 4, 1879.

To all whom it may concern Be it known that 1, EDWARD E. QU1MBY,of Orange, New Jersey, have invented certain Improvements in Centrifugal Liquoring Apparatus, of which the following is a specification.

My improvements relate to the class of devices used for packing the interstices between the molds in the centrifugal machine and the portions of the basket with which they are in proximity, for the purpose of preventing the escape, except through the sugar contained in the molds, of white liquor introduced into the interior portion of the basket; and my invention consists in forming the inner open faces of the molds upon an incline, the top of the mold being made deeper than the bottom; and in providing a series of stationary cellsiin the `central portion of the basket corresponding in number with thenumber of molds, the open outer faces of the cells being outwardly and downwardly inclined upon an angle corresponding with that of the inner faces of the molds, and the two surfaces being ground, so as to make a tightjoint when the mold is deposited in its sea-t in the basket.

lf desired. the outer ed ges ofthe boxes may be faced with india-rubber or leather, or some other elastic material, in the ordinary manner; but the ground metallic joints will be usually found to answer the purpose.

The accompanying drawings, representing a centrifugal machine embodying my improve ments, are as follows:

Figure 1 is a top view of the basket of a centrifugal machin-e, having a portion of the top of the walls removed to exhibit the side walls of the cells. Fig. 2 is a central vertical section through the line .fr x on Fig. 1; and Fig. 3 is an isometrical perspective of my sugarmold with an inclined inner open face.

The drawings represent the basket A, of a centrifugal machine, mounted upon the usual spindle B, and provided with Vertical divisionwalls C, extending radially inward from the periphery of the basket to the inner edge of the annular plate D, which forms the top of the cells.

It will be seen that the outer edge of the an nular plate D is polygonal, its planes being respectively parallel with the inner edges of the sugar-molds E. v

On the opposed side walls c of each cell, I provide the inclined shoulders c.

It will be seen that the oor F of the cell is slightly higher thanthe floor of the outerportion ofthe basket, and that it has a straight beveled edge, F', occupying the same plane as the inclined shoulders c'. The plane d of the top of the cell is also beveled, so that the plane d', the inclined shoulders c', and the edge F of the floor of the cell are inclined in the same plane, and they thus present an inclined seat for engaging the inner inclined edges of the top, bottom, and sides of the sugar-mold E. I grind this seat, and grind the inner inclined edge ofthe sugar-mold, and so proportion the depth of the sugar-mold that when deposited in the basket it wedges itself firmly between the periphery of the basket and the inclined seat.'

The central portion G of the basket is, it will be seen, open, and forms a chamber into which the white liquor can be poured when all the molds have been deposited in their places.

The sugar-molds are provided with the usual handles e, by means of which they may be lifted.

I cla-im as my invention- In centrifugal apparatus for liquoring hard sugar, an inner circle of cells, the outer edges of the top, bottom, and sides of which are down wardly and outwardly inclined, in combination with an outer circle of sugar-molds, the inner open faces of which are correspondingly inclined, substantially as and for the purpose set forth. i
